B.4 Thin covering assemblies over waterproofing layers in mortar beds

B.4 Thin covering assemblies over waterproofing layers in mortar beds according to DIN 18195

The sloped support structure is protected against permeating water with a waterproofing assembly that meets the requirements of DIN 18195. Schlüter®-TROBA-PLUS 8G is installed as a drainage membrane between the waterproofing layer and the load distribution layer (screed) to drain away seepage. This load distribution layer of sand and cement screed or pervious mortar is installed as a thin layer, using the Schlüter®-BEKOTEC-DRAIN system. The natural stone pavers are embedded in the fresh mortar.

Capillary layer
Concrete slab
Sloped screed

The construction has to be sufficiently sloped (1.5 - 2%) to allow for proper drainage.
